Witnesses told police a blue Honda Prelude was speeding east on
Aviara Parkway when the driver lost control and struck a woman, who
was running with her dog, he said. The runner, who was in the
eastbound bike lane, was thrown from the impact, Boyd said.

The 31-year-old Carlsbad woman suffered a head injury and was
flown by Mercy Air ambulance to Scripps Memorial Hospital, La
Jolla, authorities said.

The driver of the Prelude continued on and struck a tree on the
driver's side pinning the driver inside, officials said.

The driver, who was in his late teens to early 20s, and a
Carlsbad resident, was pinned under the dashboard of the Prelude
and firefighters spent 19 minutes trying to rescue him from the
mangled wreckage which was nearly bent in half from the impact,
fire Battalion Chief Jim Torretto said.

He suffered serious leg injuries and possible internal injuries
and was also flown by air ambulance to Scripps Memorial Hospital,
La Jolla.

The names or conditions of the woman and driver were not
available later.

The woman's dog may also have been struck by the vehicle but it
ran off and despite an extensive search in the area, police were
unable to find it.
